:VThe presentinventionrelates, to newand'usefulbirnprovementsin cord or twine dispensers and more particularly to means-for severing, the V twine into predetermined measured lengths as,

. y An important object of the invention, is ;to

provide a twine dispenser includinga pivoted cutter operated through the medium of a pulling force exerted on the end of the twine while withdrawing the samefrom a container to sever the twine aftera predetermined length thereof has been removed.

A further object is to provide novel means for keeping the twine under tension during its withdrawing and cutting operationand to keep the free end of the twine from re entering the container.

Another object is to provide a dispenservof this character including a container for holding a .ball of'twine having a lidand. mounting the cutting mechanism. under the lidso'ut of contact with the ball to prevent interference with the free unwinding of the twine from the ball.

A still further object is to provide a device of this character of simple and practical construction, which is efiicient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of the twine container.'

Figure 2 is a vertical sectional view thereof.

Figure 3 is a bottom plan view of the lid showing the cutting mechanism mounted thereon.

Figure 4 is a top plan view of the sheave and cutter actuating cam carried thereby.

Figure 5 is a sectional view taken on a line 55 of Figure 4.

A similar twine dispenser is shown in applicants patent, No. 2,580,878, issued January 1, 1952.

Referring now to the drawings in'detail, where-- in for the purpose of illustration I have disclosed a preferred embodiment of my invention, the numeral 5 designates a cylindrical containerifor holding a ball of twih'e' 6 and'having en-fla lid *Ttelescoping thereo The lid is formed-wvith'openings Band 9 at diametrically opposite sides of its top, the free 1: end- H! of the twine being withdrawn'through opening 8 and extended across theftop of the lid and 'over the opening 9. A box-like shield ll having aneopen inner end covers the opening 8 and a box-like shield [2 covers the opening' flfl and is formed' in itstop with an opening [3" whichextends downwardly in the-side wallsof the shield to form V-shaped notches-I4 and in -formed with;-a shoulder 11. againstwhich' a which .ithefree end of -the twine is seated. The opening I3. is closed by. a hinged'cover l5.

A'stud l6 extendsdownwardly from the under-' 7 side of the lid 1 eccentrically .thereof and is sheave I8 journaled on the stud is held by a resilient U-shaped locking key [9 to space the sheave from the underside of the lid. The sheave is formed with a V-shaped groove circumferentially thereof in which the twine is seated. The upper surface of the sheave is provided with an arcuate cam 29 fixed thereto, the axis of the cam being eccentric to the axis of the sheave.

A cutter rod designated generally at 2| in-' cludes a straight outer end portion 22 pivoted on a pin 23 extending downwardly from lid 1, and a spirally curved inner end portion 24 in which the cam 20 is arranged to travel during rotation of the sheave. To the outer end of the straight portion 22 of the cutter is fixed a blade 25 which projects through opening 9 and works in the shield [2. A coil spring 3| connects the outer end of cutter 2| to the lid 1.

A pair of twine tensioning devices 26 and 21 are secured under the lid I, said devices being of duplicate construction and the device 26 being positioned adjacent opening 8. Each tensioning device comprises a ring 28 through which the twine passes and is held against the ring by a ball 29 and coil spring 30. The twine passes from the ball 6 first through the tensioning device 21, then around sheave l8 and through tensioning device 26 before passing through opening 8, the tensioning devices being arranged coplanar with the sheave l8 to hold a free end portion of the twine, pulled off the ball 6, and looped around said sheave in friction gripping engagement with the sheave.

In the operation of the device the free end of the twine is pulled through notches I 4 in shield 12 of! the ball 6, out of the opening 8, across the top of lid I, and across opening 9, the frictional engagement of the loop of the twine with the sheave rotating the sheave and causing cam 20 to ride within the spiral end 24 of cutter 2| in a direction to place the spring 3| under tension and as the cam passes beyond the free end of spiral lever 2 1 and releases the latter, the spring 3| quickly-jpulls the blade 25 abross-the twineltb sever the' same. Accordingly the repeated rotation of sheave I8 and actuation thereby of cam 20 and cutter 2| will cut the twine in predetermined measured lengths as the twine is witlr= I and pulling the twine out of theopening 8 and-- cut at the diametrically opposite opening '9', a

4 adapted. to be manually pulled off the ball across said top and other opening, a sheave rotatably mounted on the top of said lid in spaced subjacent relation thereto and parallel therewith and around which a loop of said end portion of the twine is adapted to be passed to be pulled off the sheave through said one opening. a pair of twine tensioningdevices on saidlid coplanar with sarid shaveii-fol" tension-111g s'aid loop into frictional erigalgi'nnfiwith saidsheavto cause rotation of said sheave by pulling of said loop off the free end of the twine of substantial length is lef t outside the container 5 after each cutting operation for convenient grasping to pull more twine In view the ioregoingdescription taken coniunction; with 'the accompanying. drawings itis believedi thata clear understanding of the device will be quite apparent tothose skilled in this" hend ed by the-spirit of. the invention as herein I described and the scope ofthe appended claims.
